Um. If you take your coffee like this, you're probably a psychopath.

It looks like we’re about to find out whether Susan from accounting is really a psychopath… or just a bit of a moody cow. ¯\_(ツ)_/¯

You see, a new study has found that a lot of people with psychopathic personality traits tend to take their coffee the same way.

The study undertaken by the University of Innsbruck in Austria, and published in the Appetite journal, found the Hannibal Lecters and Norman Bates of the world seem to prefer their coffee black.

To conduct the study, the researchers surveyed more than 1000 American adults. The participants took four different personality tests that examined traits like narcissism, aggression, sadism and psychopathy.

The participants were also asked about their food tastes and how they felt about sweet, sour, salty, and bitter food and drinks.

The study found the participants who enjoyed foods with a bitter taste – like black coffee, dark chocolate, and radishes – were more likely to have psychopathic, sadistic or “malevolent” personality traits.

On the other hand, those who scored high on “agreeableness” tended to prefer sweet foods and completely avoided bitter foods.

Of course, not everyone who drinks black coffee is a psychopath and not every person with psychopathic tendencies is going to prefer black coffee.

But it’s definitely going make the morning coffee run a whole lot more interesting.
